Compact thermoelectrically cooled beverage dispenser
Abstract
A thermoelectrically cooled beverage dispensing machine of the commercial
type such as used in restaurants, movie theaters and the like featuring
compact construction is disclosed. The cooling system employs a plurality
of heat exchanger fins or plates which define a void space therein in
which a fan motor is disposed, thus saving either substantial height,
width or depth in the housing containing the cooling system. The air
circulation fan motor of the cooling system is also used as the prime
mover for a magnetic drive disc which, in turn, operates a magnetically
driven liquid impeller located within a beverage container for agitating
the beverage to create a pleasing dynamic fluid display which is also a
space saving feature in thermoelectrically cooled beverage display
systems. A multi-bowl thermoelectrically cooled beverage dispensing
machine having these same advantageous features is also disclosed.

Description
BACKGROUND OF THE INVENTION
This invention relates generally to thermoelectrically cooled beverage
dispensing machines and, more specifically, to such machines which feature
heretofore unachieved compact construction.
Broadly speaking, thermoelectrically cooled beverage dispensing machines
are known in the prior art. See, for example, the thermoelectrically
cooled beverage dispenser adapted for mounting in a vehicle over the
transmission hump on a vehicle floor as disclosed in U.S. Pat. No.
4,384,512 issued to G. R. Keith on May 24, 1983. See also the
thermoelectrically cooled liquid dispenser of the commercial type which
may be used to dispense cream for coffee in restaurants as disclosed in
U.S. Pat. No. 3,445,039 issued to B. Broadsky et al. on May 20, 1969. See
also the thermoelectric water cooler disclosed in U.S. Pat. No. 3,368,359
issued to W. A. English, et al. on Feb. 13, 1968, and the thermoelectric
liquid cooler of U.S. Pat. No. 3,174,291 issued to W. R. Crawford et al.
on Mar. 23, 1965. See also the thermoelectric water cooler in U.S. Pat.
No. 4,829,771 issued to E. E. Koslow, et al. on May 16, 1989, and the
thermoelectric wine bottle cooler disclosed in U.S. Pat. No. 4,681,611
issued to H. J. Bohner on Jul. 21, 1987. Lastly, see the thermoelectric
water cooler disclosed in U.S. Pat. No. 3,310,953 issued to J. M. Rait on
Mar. 28, 1967, and the portable thermoelectric beverage chiller of U.S.
Pat. No. 4,320,626, issued to J. H. Donnelly on Mar. 23, 1982.
All of the above referenced patents disclose thermoelectric coolers for
liquid having heat exchange fins or plates except the patents to Koslow et
al. and English et al., both of which have heat exchanger tubes. The
device of English et al. is the only one of the reference patents which
does not employ forced air circulating means such as a fan or pump. Of the
group of prior art patents cited which employ both a plurality of heat
exchange fins or plates and fans, in each of those references the fan and
plates are mounted vertically in tandem, which requires a high profile
assembly, except the systems of Bronsky et al. and Rait which plates and
fans are mounted horizontally in tandem. While the latter two systems thus
save height, they sacrifice depth or width.
Also, none of the reference patents previously cited employ means for
agitating a liquid beverage in a transparent display container for the
purpose of circulating the beverage against a roof of the container to
create a flow of beverage across the roof by means of surface tension and
thence down the sides of the bowl to form an aesthetically pleasing and
appetizing dynamic fluid display. And while there is nothing new per se
about such dynamic beverage display, the use of a single prime mover to
control both air circulation through the cooling system and agitation of
the beverage in the display bowl to provide a dynamic fluid display is
new.
Accordingly, by means of my invention, these and other disadvantages
encountered in the use of prior art thermoelectrically cooled beverage
dispensers are substantially overcome.
SUMMARY OF THE INVENTION
It is an object of my invention to provide a thermoelectrically cooled
beverage dispensing machine.
It is a further object of my invention to provide a thermoelectrically
cooled multi-bowl beverage dispensing machine.
It is another object of my invention to provide a thermoelectrically cooled
beverage dispensing machine of compact construction.
It is also an object of my invention to provide a thermoelectrically cooled
beverage dispensing machine wherein a single fan motor is employed as a
prime mover for both air circulating means and an impeller for agitating a
beverage stored in the machine.
Briefly, in accordance with my invention, I provide an improved
refrigerated dispensing machine. The machine conventionally includes a
housing and a thermally conductive, magnetically permeable support plate
attached to the housing. A conventional transparent beverage container
disposed on the support plate and a drive motor disposed within the
housing are also provided. A conventional magnetic drive means
responsively connected to the motor and disposed in the housing next to
the support plate, and a magnetized liquid circulating means rotatably
disposed in the container and responsively coupled, magnetically, to the
drive means is also provided.
The improvement I provide includes a thermoelectric refrigerating system
disposed in the housing for removing heat from the support plate to cool a
beverage stored in the container, and air circulating means disposed in
the housing for drawing ambient air into the housing to extract heat from
the refrigerating system and for exhausting such air, so heated, from the
housing, the air circulating means also being responsively connected to
the motor.
These and other objects, features and advantages of my invention will
become apparent to those skilled in the art from the following detailed
description and attached drawings upon which, by way of example, only the
preferred embodiments of my invention are described and illustrated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to drawing FIGS. 1-3 there is shown, in one preferred
embodiment of my invention, a refrigerated beverage dispensing machine
generally designated 10 which includes a housing 12, a thermally
conductive, magnetically permeable support plate 14 constructed of
aluminum, stainless steel or the like, attached to the housing 12 in any
suitable manner, and a transparent container 16 disposed on the plate 14
for storing a beverage in a refrigerated state prior to being dispensed.
The support plate 14 contains a circular recess 18 in which a circular
collar 20 defining a circular opening in a base plate 22 of the container
16 rests, the floor of support plate 14 in the recess 18 thus forming a
portion of the floor of the container 16. A resilient circular gasket 21
is disposed between and around the vertical defining walls of the recess
18 and collar 20 to prevent liquid flowing on the floor of the recess 18
from seeping out of the container 16. The opening defined by the collar 20
contains a cap or cover 24 having a series of apertures 26 therethrough
located on and around a central portion thereof. A conventional magnetized
agitator disc or impeller 28 is rotatably disposed between the cover 24
and the support plate 14 in a central circular portion of the recess 18
under the apertures 26. The impeller 28 is rotatably mounted on a
shouldered sleeve bearing 29 which is, in turn, fixedly but removably
mounted on a stationary shouldered pin 30. A three legged frame 31, only
two legs of which are shown, is connected on distal ends thereof to and
around an upper surface of the cover 24 and contains a central portion
which is spaced above a central portion of the circular cover 24 and
support plate recess 18. An upper end of the pin 30 is held in place
against the central portion of the frame 31 by means of a washer 32 and
screw 33. The pin 30 extends from the central portion of the frame 31
downward through a central opening in the center of the cover 24, through
the sleeve bearing 29 and surrounding impeller 28 and through an opening
in the support plate 14 formed in the center of the recess 18. A shoulder
34 on a lower end of the pin 30 bears against the underside of the support
plate 18, whereby the pin 30 joins the cover 24 to the support plate 18.
The cover 24 is thus held tightly in the recess 18 between the washer 32
and screw 33, on one end of the pin 30, and the shoulder 34 and support
plate 18 on the other end thereof. However, the rotatable impeller 28 is
held off the floor of the support plate 18 by a lower shoulder of the
sleeve bearing 29 so that the impeller 28 will be readily rotatable.
As is conventional, the upper surface of the disc shape impeller 28
contains a series of raised fins or blades 35 which extend radially
outward from the center of the impeller 28 to its periphery. Thus liquid
which flows downward through the apertures 26 in the cover 24 is slung
outwardly by the rotating impeller 28 so as to be forced through an
expanding spiral path formed by walls 36 which depend from the cover 24
and which define a spirally extending channel 37 in a horizontal plane. As
the beverage circulates in such an expanding spiral path around and across
the support plate recess 18, it is cooled by the refrigeration system as
later described. Ultimately, the spiral path under and about the cover 24
leads to a riser tube 86 wherein the cooled beverage rushes upwardly to
splash against a roof of the transparent container 16 to thus flow down
around the sides of the container 16 to join the remaining liquid, thus
creating an aesthetically pleasing, appetizing and dynamic fountain-like
display.
The body of the impeller 28 below the fins 35 contains a series of
magnetized, ferromagnetic elements 38 disposed therearound which are
completely encased in plastic 39 so as not to contact the beverage in the
container 16 and thus be subject to the release of rust products. A
rotatable magnetic drive disc 40 is located just under the support plate
14 in registry with the impeller 28 and is connected by means of a collar
41 and set screw 42 to a drive shaft 43a of an electric motor 44. The
magnetic drive disc 40 is located within a circular opening 45a and b
formed in and extending through a cold plate 46 and a hot plate 48
respectively. The opening 45a and b is sufficiently larger in diameter
than the diameter of the drive disc 40 to allow the latter to turn freely
on the shaft 43a without rubbing the opening defining surfaces of plates
46 and 48. A series of conventional thermoelectric heat pump modules 50,
such as those manufactured by Materials Electronic Products Corporation,
990 Spruce Street, Trenton, N.J. under the trademark MELCOR, are
sandwiched between and spaced around the cold and hot plates 46 and 48.
The plates 46 and 48 are constructed of a thermally conductive material
such as aluminum plate or the like and are mechanically connected tightly
together with the modules 50 tightly sandwiched therebetween by means of
machine screws 52, taking care that the plates 46 and 48 do not touch one
another. The screws 52 are tapped into the cold plate 46 and are insulated
from the hot plate 48 to prevent heat flow therethrough and consequent
loss of cooling efficiency of the assembly. In the present example, the
head of each of the screws 52 seats within an oversize countersink 54
formed in a bottom surface portion of the hot plate 48 against a thermally
insulative shouldered fiber washer 56. The shank of each of the screws 52
extends through a sleeve portion 60 of the washer 56, which is inserted in
an oversized hollow shaft 58 in the hot plate 48 and is thereafter
threaded into a lower surface portion of the cold plate 46. A thermally
conductive joint compound is coated to the opposing surfaces of each of
the plates 46 and 48 which contact the modules 50 to assure good thermal
contact. I recommend using Type 120 thermal joint compound as manufactured
and sold by Wakefield Engineering, of Wakefield, Mass.
An upper surface of the disc shaped cold plate 46 is connected to the
underside of the circular recess 18 of the support plate 14 so as to be in
efficient thermal contact therewith. I recommend the use of a suitable
epoxy glue impregnated with aluminum filings such as that sold under the
trademark Delta Bond 154. The hot plat 48 is rectangularly shaped and
contains a series of spaced apart, paralleled extending channels in a
lower surface portion thereof in which are inserted edges of a plurality
of rectangularly shaped cooling fins or heat exchanger plates 62. A lower
central portion of the plates 62 defines a void space 64 in which the
motor 44 is disposed. By placing the motor 44 within a space defined by
the plates 62, as opposed to being placed below or beside the plate
package, considerable space saving is realized which materially
contributes to the compactness of the machine 10. In addition to driving
the magnetic drive disc 40, the motor 44 also drives a cooling fan 66
located on a drive shaft 42b below the plates 62 and a cover plate 70 in a
fan housing 72. The drive shaft 42b is, of course, an extension of the
shaft 42a. The fan housing 72 contains a circular opening 74 in the base
thereof and the cover plate 70 contains a series of circular openings 76
to permit ambient air to be drawn by the fan 66 through the fan housing 72
and forced into and between the heat radiating plates 62. The housing 12
is divided vertically into an air inlet lower portion 78 and an air outlet
upper portion 80 by means of strips 82 of low density, closed cell,
polyurethane foam which extend completely around the fan housing 72 and
extend between the latter and the inside surfaces of the sidewalls of the
housing 12 in an essentially air tight manner.
Ambient air is thus drawn by the fan 66 into the air inlet lower portion 78
of the housing 12 through a first series of louvers 84 located below the
strips 82, thence through the opening 74 and the fan housing 72 and is
thereafter forced through the cover plate openings 76, heat radiating
plates 62, and, finally into the air outlet portion 80 of the housing 12
above the strips 82 where it is exhausted back to ambient through a second
series of the louvers 84 located above the strips 82. The fan motor 44
thus drives both the air circulating fan 66 and the magnetic drive disc
40, the latter being magnetically coupled to the magnetized impeller 28
for circulation of the beverage in the container 16 to both cool the same
and create a dynamic fluid display in the transparent container 16. As the
impeller 28 rotates, liquid beverage stored in the container 16 which has
flowed downward through the openings 26 in the cover 24 is agitated in a
well known manner to flow through the spiral or vortex guide formed on the
underside of the cover 24 by the walls 36 until it reaches the riser tube
86 wherein it is forced against a roof of the container 16, thus causing
it to flow down all sides of the container 16 to present a pleasing and
appetizing appearance.
The electrical circuitry of the thermoelectric cooling assembly includes
the modules 50, electrically connected to one another in a suitable and
well known manner between an output line 88 of a conventional full wave
bridge rectifier 90 and ground 92. FIG. 2 shows the modules 50 being
electrically connected in series with one another but they could also be
connected in parallel. Any a.c. ripple emitted by the rectifier 90 is
essentially shorted to ground 92 in the usual, well known manner by a
suitable capacitor 94. The rectifier 90 receives an a.c. input potential
from a secondary winding of a transformer 96, the primary side of which is
connected across the fan motor 44. A single pole, double throw switch 98
connects a commercial a.c. potential to the fan motor 44 and the primary
winding of the transformer 96 when closed. A conventional thermostatically
controlled ON/OFF switch 99 connected between a secondary winding of the
transformer 96 and the rectifier 90 allows the thermoelectric cooling
system to be automatically activated when the cold plate temperature is
above a predetermined value and de-activated otherwise. A second secondary
winding of the transformer 96 can be connected to a second bridge
rectifier circuit, similar to the rectifier 90, to supply a d.c. operating
potential to a second thermoelectric refrigerating system such as used in
the dual bowl assembly shown in FIGS. 4-5 as will now be explained.
Referring now to FIGS. 4-5 a dual bowl thermoelectrically cooled beverage
dispensing machine 100 is shown which includes a pair of transparent
beverage containers 102, 104, each of which has a circular opening in it's
base defined by a collar 106 which rests within a circular recess 108a and
b, respectively, formed in a magnetically permeable, thermally conductive
support plate 110. The plate 110 is attached to sidewalls of a housing 112
in any suitable manner. The sidewalls of the housing to which the support
plate 112 is attached may be made of metal, molded plastic or other
suitable material. The circular openings in the base of each container
102, 104 contain a removable cover 114 which defines a spiral or vortex
guide of usual, well known type similar to that shown in the cover 24 of
the machine of FIG. 1. The cover 114 contains openings through an upper
central surface portion thereof which permits a beverage in the container
thereabove to flow downward into the vortex guide. A rotatable
magnetically driven impeller 116 located within a central portion of the
vortex guide under each of the covers 114 circulates the beverage to a
corresponding riser 118 for the same purposes and in the same manner as
shown and described in relation to FIG. 1.
The machine 100 also includes a thermoelectric cooling assembly associated
with and disposed below each of the support plate recesses 108a and 108b.
Each of these assemblies is identical to the one shown and described in
relation to FIGS. 1-3 and contains a cold plate 120, a hot plate 122, and
a series of thermoelectric cooling modules 124 sandwiched therebetween.
Attached to the base of each cold plate 120 is a series of rectangularly
shaped heat radiating plates 125. Each bundle of plates 125 contains a
space 126 in which a different fan motor 128 is disposed, which fan motors
operates both a magnetic drive disc located in a central space within the
hot and cold plates 120 and 122, and a fan located in a fan housing 130,
the same as shown and described in the previous example.
A series of strips 132 of closed cell polyurethane foam disposed between
and around the housing 112 and the fan housings 130 divides the interior
of the housing 12 into a lower air inlet portion 134 and an upper air
outlet portion 136. The fans in the housings 130 draw ambient air through
baffled slots 138 located below the strips 132 and into circular openings
in the bottoms of each of the fan housings 130, the same as shown in the
previous example. Similarly, air drawn into the fan housings 130 is forced
upwardly between the plates 125 and thence forwardly and rearwardly in the
housing 112 as viewed in FIG. 4, above the strips 132 to ultimately be
exhausted through baffled slots 140 located above the strips. The base of
the housing 112 shows a transformer 142 similar to the transformer 96 of
FIG. 2, capacitors 144, similar to the capacitor 94 of FIG. 2, and other
components mounted thereon for use in the electrical circuitry of each of
the thermoelectric cooling assemblies of the machine 100. Each of these
circuits may be identical to the circuit shown in FIG. 2. The circular
recesses 108a and 108b are thermally insulated from bands 146 which
surround the cold and hot plates 120 and 122 by means of low density
closed cell polyurethane foam linings 148. A resilient circular gasket 150
lies snugly between the collars forming the openings in the base of the
containers 102 and 104 and the circular periphery of the recesses 108a and
108b in the support plate 110, to provide a liquid tight seal between
these two elements to prevent beverage from leaking from the base of the
containers 102 and 104 onto the support plate 110 beyond of the recesses
108a and 108b.
Although the present invention has been described and shown with respect to
specific details of certain preferred embodiments thereof, it is not
intended that such details limit the scope of my invention other than as
specifically set forth in the following claims.
